Answer Engine Optimisation (AEO) is the practice of optimising your business to be cited inside AI engines — ChatGPT, Perplexity, Google AI Overviews, Gemini, and Claude. It's the new layer of search visibility that's emerged since 2023, and most UK tradesmen are completely invisible inside it.
Here's why it matters: when a homeowner under 40 wants an electrician, they increasingly ask ChatGPT or Google AI Overviews 'who's a good electrician near me' before they Google it the traditional way. The AI engine gives them a few recommendations — usually based on what's been published online, what's cited in trusted directories, and what structured data the AI can extract from a business's website. If your business has no schema markup, no llms.txt, no FAQ pages structured for AI extraction, and no citations on the sources AI engines trust, you're not in those recommendations. Your competitors are.
AEO is the technical and content work needed to fix that. It overlaps with SEO — both rely on a well-structured site and authoritative citations — but the optimisation targets are different. SEO targets the Google ranking algorithm. AEO targets what AI engines decide to quote.
